A homeowner in St John's Wood, NW8 wanted to upgrade an old panel radiator to a modern designer column radiator β but was understandably cautious about a heating job disrupting a recently finished interior. Before Ralf lifted a single tool, the entire work area was sealed with protective foil sheeting to guarantee zero stains, spills, or dust marks on the flooring.
A radiator installation involves draining and disconnecting existing pipework, which inevitably carries some risk of drips and residue even when carried out carefully. Rather than treating this as an unavoidable side effect, Ralf treats full floor and surface protection as a standard part of every job β not an optional extra offered only on request. In a property with original flooring or a recent renovation, this is the difference between a heating upgrade that leaves no trace and one that creates a second job to fix afterwards.
With the area fully protected, the old radiator was removed and the new designer column unit fitted, connected, bled, and tested for even heat output across every column. The work area was left exactly as it was found β no dust, no marks, no cleanup required by the homeowner.
This is the standard Pristine Gas Ltd holds every job to, whether it's a single radiator upgrade or a full boiler installation: the technical work matters, but so does the condition the property is left in afterwards.

Not with proper protection in place. Draining and disconnecting pipework carries some risk of drips and residue, so we seal the work area with protective foil sheeting on every job as standard, not as an optional extra, to guarantee no stains, spills, or marks.
Yes. A single radiator can be swapped for a designer column unit on its own, connected to the existing pipework and boiler. It's often paired with a power flush of that radiator's circuit to make sure the new unit isn't immediately fed sludge from the rest of the system.
